That is kinda weird. I'd say it may be a driver issue that doesn't support dual monitors. Are they both VGA or DVI. I don't know if your trying one VGA and one DVI that may cause a issue. Thats about my only 2 guesses. What graphics card are you installing it on?
Edit:
Not sure what that program is i just use the one desktop background in dual view. Maybe run a search for it I know someone posted it with something along the lines of dual desktop backgrounds or something. If your missing the taskbar 1 is still set as primary with the second in dual view extended thats kinda weird. Unsure what to suggest for ya there. Thanks for the rep
That may cause a Issue. Don't hold me to that but it would make some sense. Try googling dual view displays with a combo of VGA/DVI and see if there are any hits of people posting problems of running 2 displays with that setup. I'm running dual VGA's myself with DVI>VGA adapters. So that may very well be your problem just don't hold me to it just a hypothesis
Ok well I updated drivers and when I ran my big monitor at native res it got disproportioned and I had to scroll the screen over to see it all, and it was pretty blurry, so I rolled back the drivers.
Now I have everything taken care of and working good. But the drivers I got from the nVidia site were bad.
Anyways, whats something I split wallpapers with? What program changes wall papers per background?
